Critics shouted "Shame! Shame! Shame!," reports CNN.

The DNC is off to a rocky start with the abrupt resignation of longtime chairwoman Debbie Wasserman Schultz over the weekend amid a searing email scandal, during which hacks revealed she showed favoritism toward Democratic presidential nominee Hillary Clinton.

On Monday, Wasserman Schultz was booed when she began to address a Florida delegation breakfast at the convention in Philadelphia, Pennsylvania, a day after she announced plans to resign as the chair of the Democratic National Committee, writes ABC News:

An event organizer had to actively try and quiet the crowd’s boos before Wasserman Schultz began speaking.

She started by bringing up the deadly shooting in Fort Myers, Florida, but the boos continued before she eventually acknowledged her resignation.

“I can see there’s a little bit of interest in my being here, and I can appreciate that interest,” she said.

The Associated Press reports the convention kicked off to “much bigger demonstrations than the Republican convention and much higher temperatures, as the region copes with an oppressive heat wave.”
